What is Guerilla User Testing? A Quick Guide for UX Researchers
What is Guerilla Testing?
Guerilla testing (also known as “guerilla user testing”) is an informal, low-cost technique used to gather immediate user feedback about a product or prototype. Unlike lab-based or formal usability studies, guerilla testing typically involves approaching people in real-life scenarios—like coffee shops, college campuses, or conference lobbies—and asking them to perform quick tasks or offer feedback on a product, concept, or prototype.
Key Characteristics of Guerilla Testing
Low Cost: No need for expensive equipment or research labs.
Fast & Agile: Collect immediate feedback without an extensive recruitment process.
Realistic Context: Test in environments where users naturally spend their time.
High-Level Insights: Great for initial impressions, early-stage prototypes, or concept validations.
Whether you’re building a new mobile app, website, or physical product, guerilla testing helps you rapidly validate your ideas with minimal resources—perfect for startups, small businesses, and teams under tight timelines.

Why Guerilla Testing Matters for Modern UX
Immediate Feedback Loop
In the early stages of product development, speed is crucial. Quick rounds of guerilla testing can reveal glaring issues or confirm that you’re on the right track. Rather than waiting weeks for a formal study, you can gather user insights in hours or days.Cost-Effectiveness
Traditional user research can be costly, especially if you need to rent lab space or provide incentives for participants. Guerilla testing often happens spontaneously in public spaces, dramatically lowering your overhead.Real-World Context
Observing how users interact with your product in natural settings provides more authentic data. For example, you might discover that bright sunlight makes your on-screen text hard to read or that an app’s navigation is too confusing when someone is on the go.Inclusive & Diverse Feedback
By conducting concept tests or product tests in public, you naturally encounter a broader cross-section of demographics. This helps you gather a more diverse set of opinions compared to a curated, formal participant list.
5. Supports Iterative Design
Because guerilla testing is quick and frequent, it dovetails perfectly with iterative design approaches. Gather feedback, make updates, test again—a cycle that keeps your product design and user experience on point.
Setting Up a Guerilla Test
Define Clear Objectives
What are you hoping to learn? Are you testing basic usability, visual appeal, or feature desirability? A short list of goals keeps your guerilla tests focused and valuable.Identify Suitable Test Locations
Look for places where your target audience naturally congregates—coffee shops, libraries, tech meetups, or community centers. Make sure you have permission (where needed) to approach people.Prepare Quick Tasks
Keep tasks short (2–5 minutes). Users in public won’t have time for a lengthy research session. Simple tasks, such as “Find the product page on this website” or “Add an item to the cart,” are ideal.Create a Simple Prompt
Introduce yourself and your research in a friendly, concise way:
“Hi, I’m testing a new app concept. Would you be open to giving me 2 minutes of your time to try it out? I’d really value your honest feedback!”Record Observations
We recommend leveraging video to understand user actions, facial expressions, or comments. A video research app like indeemo works well. You can also ask users to share their thoughts out loud as they test.
Incentives & Gratitude
Although guerilla testing is often unpaid, even small tokens of appreciation—like a coffee voucher—can encourage participation and leave a positive impression.
How Indeemo Elevates Guerilla Testing
While guerilla testing is typically associated with face-to-face interactions, market research video tools like Indeemo can streamline and scale your approach, making it easier to gather quick feedback from participants—whether you meet them in person or connect online.
1. Seamless In the Moment Insights
Indeemo is a mobile-first tool designed to capture authentic in-the-moment insights. This complements guerilla testing by allowing participants to record their user experiences (through video, photos, or text) immediately as they happen. If you’re running a guerilla test in a public space, you can quickly onboard users to the Indeemo app, where they can:
Upload short videos of them using your prototype or app.
Capture screen recordings to show how they navigate a digital product.
Provide quick text or audio feedback on usability, layout, or content.
2. Real-Time Feedback Collection
One of the biggest advantages of guerilla testing is its immediacy. With Indeemo, you can gather, organise, and review user feedback in real time. This allows your design team to make rapid changes and iterate quickly, even within the same day.
3. Remote Participation
Can’t reach your target audience in person? No problem. Indeemo facilitates remote research by letting participants record their experiences from anywhere. You can recruit users online (e.g., through social media, email lists) and have them complete tasks on their devices. This blends the spontaneity of guerilla testing with the convenience of remote user research.
4. Easy Task Setup & Management
With Indeemo, you can create tasks for participants to complete. These tasks guide users through specific actions—such as exploring a new feature or sharing their initial thoughts on a design concept. You can then monitor task completion and user submissions in a centralised dashboard.
5. Collaborative Analysis
All user-generated content is stored on Indeemo’s secure platform, ready for your entire team to access and analyse. Comments, transcripts, word clouds, and generative AI help you quickly identify patterns or issues, enabling data-driven decision-making.
Best Practices for Successful Guerilla Testing
Keep Tests Short & Focused
People are more willing to participate if they know the session will only last a few minutes. Focus on 1–2 core tasks or questions.Test Early and Often
Guerilla testing isn’t a one-and-done method. Like iterative research, run small tests regularly, each time you push a new feature or refine your design.Use Open-Ended Questions
Encourage participants to speak freely. Ask open ended questions like:
“What do you think about this feature?”
“How would you describe your experience so far?”
This often reveals more insights than structured questionnaires.Maintain Professionalism & Respect
Even though your testing is informal, always respect people’s time and privacy. If they’re not interested, politely move on.Combine Online & Offline Approaches
For a broader reach, supplement in-person guerilla tests with remote tasks on Indeemo. You’ll capture a wider variety of user feedback without losing that quick, agile edge.Iterate on Feedback Quickly
The real power of guerilla testing is in rapid iteration. Once you identify an issue, fix it fast. Then, test again.
